News tagged with absorption spectrum

The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...

A team of astronomers from Leiden University, The Netherlands, measured the chemical fingerprint of the smallest aromatic molecule. According to astrochemical models this molecule should be highly abundant ...

(Phys.org) —A research team led by FOM workgroup leader Prof. Dr. Wim Ubachs and Dr. Rick Bethlem has once again demonstrated that the mass ratio between electrons and protons has remained the same over ...

An international team led by the University of New South Wales has studied a distant star where gravity is more than 30,000 times greater than on Earth to test its controversial theory that one of the constants ...

(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short ...

(Phys.org) —A University of Illinois research group brought together aspects of condensed matter physics, semiconductor device engineering, and photochemistry to develop a new form of high-performance solar ...

(Phys.org) —A team of physicists from Russia's Institute of Applied Physics, Russian Academy of Sciences, has built an exceptionally sensitive spectrometer that they claim, is the first to measure water ...

A new technique developed by U of T Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells, according to a recent paper published in the journal Nano Le ...

Center for Nanoscale Materials (CNM) users from Northwestern University, working together with the Nanophotonics Group at the Argonne National Laboratory, report the functionalization of porphyrin-based metal-organic ...

(Phys.org)—Can windows, tablets and e readers turn light into power? Can a surface coated with solar cells take sunlight and the glow of bulbs and change them into energy? As reported in Technology Review, expert ...

(Phys.org)—Quantum physicists from ETH Zurich have discovered special properties in a laser, thanks to which portable devices can be built to analyse gases and liquids accurately and reliably in the future.

The driving mechanism of the greenhouse effect, and the underpinning of modern anthropogenic warming, is the absorption, emission, and transmission of infrared radiation by atmospheric gases. The heat-trapping ability of ...
